200 Mesh
Introduction
Ceramic sand powder refers to that ceramic foundry sand with particle size less than 200 mesh.
It is also made from high-quality bauxite through calcination, electrofusion, granulation, sieving and other processes. It is often separated from the particle sand for special use rather than moulding and casting.
Physical and chemical properties
| Al2O3 | Fe2O3 | SiO2 | TiO2 | Refractoriness | Bulk density | Thermal conductivity |
| 65-85% | 5%max | 12-25% | 3-4% | ≥1800℃ | 1.95-2.05g/cm3 | 1200℃ 5.27W/M.K |
| Color | PH | Angularity | Grain Shape | Specific density | Expansion rate | Grain size |
| Brown | 7-8 | 1.1min | Spherical | 3.4g/cm3 | (20-1000℃) 6*10-6/℃ | Below 200 mesh |
Application
Foundry coatings
Ceramic Foundry Sand Powder is a good choice of foundry coating filler for its controllable particle size, spherical shape, ideal sintering point and melting point, high thermal conductivity, low thermal expansion and minimum reactivity towards many kinds of metals being cast. It is an effective substitute of much expensive materials such as zircon sand flour.
3D printing
Ceramic Foundry Sand Flour can be graded to a “single” mesh distributed form, it is rather suitable in 3D printing processes. Many parts of complicated castings have been produced by 3D with approving quality in a very short period.
Features:
· High refractoriness.
· Spherical shape.
· Low thermal expansion rate.
· Inert chemical performance.
· Intrinsic hardness and wear resistance.
· Good thermal conductivity.
